Final answer:
The feature Tyhurst described as common to transitions, similar to stress, is trajectories.
Step-by-step explanation:
The feature Tyhurst described as common to transitions, similar to stress, is a) Trajectories.
A trajectory refers to a path or course of development or change over time. In the context of transitions, a trajectory represents the direction and progression of a change or transition that an individual goes through. It involves moving from one state or phase to another, which can be accompanied by stress and challenges.
For example, when someone transitions from being a student to entering the workforce, they may experience stress and uncertainty about the new responsibilities and expectations they face. This trajectory involves a significant change in roles and responsibilities, which can be similar to experiencing stress.
